It can make a huge difference, easily offsetting the weight of the cables. The battery in the car now sits relatively close to the COG, which means it has minimal impact on COG, at least the horizontal component.
If you move it further out on the rear ARM (moving it towards the rear of the car and further from the COG) the same weight gets amplified and move the the COG much more effectively. As someone above mentioned, its just like a see-saw (basic lever).
This is used in experimental aircraft all the time. you can offset a significant portion the weight of a 200lb engine just by putting the battery in end of the tail cone.
